In the 2011 draft, take Julio Jones #6 overall instead of trading down with Atlanta. In round two, Kaepernick was drafted #36 and the Browns selected at #37. A modest move up the board would've secured the quarterback. The subsequent year - take Trent Richardson in the 2012 draft as they did anyway.

(Obviously the Browns 2011 record could've been different in this scenario, meaning they wouldn't be in position to get Richardson. But... yeah)

Buffalo Bills could have an offense consisting of... A.J. Green and Colin Kaepernick

How?

In the 2011 draft, Buffalo passed on Green and Julio Jones to take Marcell Dareus. In the second round, they drafted 'bust already' Aaron Williams one pick before Andy Dalton and Colin Kaepernick were taken by Cincinnati and San Francisco respectively.

This is less convoluted than the Browns projection given both picks were readily possible in the same draft. Instead of owning one of the more explosive offenses in the NFL, Dareus and Williams are part of one of the most expensive and inept defenses in the league.
